# Documentation

data PathCompletionInfo #

Information used to query and build path completions.

Note that pathSegment combined with queryDirectory results in the original prefix.

Example: When given the written prefix, `dir1/dir2/fi`, the resulting PathCompletionInfo would be:

       pathSegment = "fi"
       queryDirectory  = "dir1/dir2/fi"
       ...

Fields

- pathSegment :: Text

  Partly written segment of the next part of the path.

- queryDirectory :: FilePath

  Written part of path, in posix format.

- workingDirectory :: FilePath

  Directory relative to which relative paths are interpreted, platform dependent.

- isStringNotationPath :: Maybe Apostrophe

  Did the completion happen in the context of a string notation, if yes, contains the state of the string notation.

pathCompletionInfoFromCabalPrefixInfo :: FilePath -> CabalPrefixInfo -> PathCompletionInfo #

Takes an optional source subdirectory and a prefix info and creates a path completion info accordingly.

The source directory represents some subdirectory of the working directory such as a path from the field `hs-source-dirs`.

If the source subdirectory is empty, then the working directory is simply set to the currently handled cabal file's directory.

sourceDirsExtractionLibrary :: Maybe StanzaName -> GenericPackageDescription -> [FilePath] #

Extracts the source directories of the library stanza.

sourceDirsExtractionExecutable :: Maybe StanzaName -> GenericPackageDescription -> [FilePath] #

Extracts the source directories of the executable stanza with the given name.

sourceDirsExtractionTestSuite :: Maybe StanzaName -> GenericPackageDescription -> [FilePath] #

Extracts the source directories of the test suite stanza with the given name.

sourceDirsExtractionBenchmark :: Maybe StanzaName -> GenericPackageDescription -> [FilePath] #

Extracts the source directories of benchmark stanza with the given name.

extractRelativeDirsFromStanza :: Maybe StanzaName -> GenericPackageDescription -> (GenericPackageDescription -> [(UnqualComponentName, CondTree b c a)]) -> (a -> BuildInfo) -> [FilePath] #

Takes a possible stanza name, a GenericPackageDescription, a function to access the stanza information we are interested in and a function to access the build info from the specific stanza.

Returns a list of relative source directory paths specified for the extracted stanza.
